Although experience is the important method in the shaft parts straightening multi-steps technology at present, easily programmed and simple carried out Parts material bad harmonious and axis curve variously make the method only in the automatic straightening process for the simple large-scale simple parts General predictive control has been utilized in many fields, but few papers report the plastic deformation predictive control The new shaft parts straightening technology general predictive model has been built up based on stroke controlled shaft parts straightening technology equation in this paper, and nonlinear control for the same remainder deformation has been brought about according to the general predictive algorithm The experiment shows that the algorithm can meet precise straightening quality, and the control effect will be better with control steps increased
